Terminal State Control Status Codes

Status Message/Description

No error detected

The request was performed with no detected problem.

Terminal must be disabled

For a terminal control request the terminal must be disabled.

Too many terminals on port

No more terminals can be added to the requested port unless an existing one is moved to another port or deleted.

Invalid terminal number

A request has been made to a terminal which has not been initialized, or the terminal number is outside of the valid range of terminals for the interface.

Invalid request code

The request code was not recognized by the multiplexer firmware.

Terminal not assigned to port

The terminal must be initialized before further control requests can be made.

Protocol not loaded

The requested protocol is not currently available on the multiplexer. The terminal type is wrong or a new download file with the required protocol should be obtained.

Invalid port number

Port numbers must be in the range zero (0) to seven (7) for Z7200A and Z7400A cards; zero(0) to one(1) for the Z7350A card, and zero(0) to three(3) for the Z7300A card.

Group not disabled

All other terminals on the same port and with the same group poll address must be disabled before a terminal's configuration can be changed.

New group must be disabled

All other terminals on the same port and with the same group poll address must be disabled before a terminal can be added to that group.

Not allowed for this terminal

Not used.

Invalid subchannel number

Protocol detected error

The protocol does not handle this type of request or the request is invalid.

Terminal must be deleted

The terminal must be deleted before changing the port, subchannel or protocol assigned to it.

Protocol table sizes too small

The protocol requires a larger table (typically terminal table).

Request format error

For a set terminal parameters request, the associated buffer length is zero or the request data has an invalid format.

No buffer space

There are no free buffers on this port to process this message.

Retryable error occurred

An internal status code used between the driver and firmware to indicate that a request should be retried at a later time.

Buffer size is illegal

The length of the request data for a set terminal parameters request is not valid.

Invalid request code (internal error)

The destination of the request did not recognize the specified request code. This should never happen.

Deferred request (internal usage)

An internal status code used between the driver and the firmware to indicate that the request will have a deferred response.
